MULTICOLOR-PRINTING MACHINE.

Application filed November 26, 1921.

Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Multicolor Printing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enl l0 able others skilled in the art to which it appertains to make and use the saine.

This invention relates to printing vmachines and more particularly to multi-color printing machines, the main objects of the present invention being an improvement on )atent No. 1,240,159, granted ,to me September 11, 1917. y

One of the objects of my invention is the provision of a yprinting machine comprising a rotatable carriage provided with a plurality of sets of rollers and means for causing the rollers toautomatically engage the properinking discs and convey the ink to the proper set of type in accordance with the color whereby each set of type will be inked with the proper: color.

A further object of the invention is the provision of means for diverting each carriage supporting form from its circular path' and directingit along a straight line at the time it is passing beneath the printing cylinder, such means being utilized to prevent any shock or jar from being conveyed to the type supporting carriage so that the proper printing will be carried out,

A further object of the invention is the provision of means for operating additional inking discs and for dividing the ink fountain whereby several colors may be used in the printing, the -means for operating the discs being utilized-to operate a single disc or a -pair of discs. y

With the above and other objects in view3 the invention consists in the novel features of construction, combination and arrangement of parts hereinafter more fully set u forth,- pointed-out in the claimsv and shown in thel accompanying drawings, in which: Figure 1 1s a plan view of the press with parts thereof broken away toillustrate details of. construction; y

Referring now more particularly to the drawings, the numeral 1 indicates a supporting member formed of a plurality of radially projecting supports and mounted upon the upper end of the member 1 is aibase 2 which isbolted or otherwise secured to the supporting member 1 as illustrated in Fig. 2. At the center of the supporting member 1, is a recessed portion 3 and extending upwardly from the base 2 is a bearing sleeve 4 which communicates directly with the recess 3 and in which is mounted the central supporting standard or hub 5 of a rotary table 6. Keyed'to the lower end of the standard 5 is a bevel gear 7 arranged within the recess 3 and cooperating with a gear 8 upon the inner end of the operating shaft 9,' said lshaft being suitably mounted in bearings 10 and having fast and loose pulleys at its outer end so that it maybe rotated from From the hub 5 radiates a plurality of spokes l1 carrying at their outer ends the table 6 shownl in the drawings as of skeleton formation and made up of two rings whereof the outermost travels on the supporting casters or wheels 12 which tend to support the out-er edge of the table 6 in spaced relation with thebase.

In order ,to accommodate various colors of ink, I have shown in Fig. 1 wherein a single inl-zing disc may be replaced bytwo disc and also for doublediscs.

i In Fig. l I have illustrated. the manner of supporting two discs in the place of asingle disc, said support comprising av standard 20 having-radiating arms extending inopposite directions and provided with upwardly proj ectingy pins 21l upon which4 the discs 22 are mounted. I have also illustrated means in the form of a partition 23 whereby the ink fountain 16 may be divided to form two separate chambers for the reception of two different colored inks to correspond with the spaced discs arranged adjacent the fountain. F rom the illustration in F ig. 1, it will be apparent that three or more colors may be utilized in printing by changing any of the single discs 13 to the double discs 22 and placing the partition 23 within the ink fountain 16.

For the purpose of illustration l will describe the device as using three colors although it will be apparent from the above that various colors may be utilized by changing the discs and. partitioning the fountains. In the drawings, I have illustrated three chases or type carriages, one with red, another with green and the third one with blue. For each disc or set of discs I prefer to use a set of three rollers generally indicated as at 24, each set of rollers being raised and lowered by suitable mechan'ism to apply ink to the proper chase at the proper time. Extending upwardly through the hub is a pillar 25 and secured to the head of this pillar at the upper end thereof is aspider 26 carrying in the present case, three arms 27 each having, at its outer end, an upright plate 23 provided with a series of slots 29 and rising rigidly from the base 2 is a similar plate 30 having an equal number of upright slots 31, in. said slots rest the trun- :is nions 32 of the rollers 24 and each roller has on its trunnions wheels 33 spaced according to the gage of the rails upon which. they run.

Surrounding the central portion of the table v6 is an annular track-way having opposed '10 depressions formed therein to receive the wheels 33 upon the inner ends of the set of rollers which are used to apply the ink to the chases indicated as printing` the blue impressions upon the material. The depres- 1 vsions formed in the annular track-way are generally indicated by the numeral 34. An intermediate set of depressions as at 35 are formed in the track-way and are used for applying green ink to the proper chase. A third set of depressions is indicated at 36. said depressions being used for causing the rollers 24 which are applying the. red ink to the proper chase to move over the disc previously supplied with the ink and also causing therollers to contact with the proper chase when it reaches that point beneath the rollers.

An annular track-way is also formed upon the outeredge-of the table 6 and is pro- .vided with depressions corresponding with the depressions formed upon the. inner annular track-way whereby the wheels which support therollersupon both ends will be dropped .downwardly into kthe proper Adepressions at the proper time. As illus- CII lll

trated, the depressions 37 are formed opposite the depressions 34 so that when the rollers which are operating upon the blue ink, reach the position shown inlfig. 1, the wheels thereof will more within the depressions 34 and 37, dropping the rollers downwardly so that they will engage with the disc 13 and obtain ink therefrom. Therefore, when the chase which contains the type for printing the blue impression reaches the point where the rollers are now located, through the rotation of the table 6, the rollers will be again lowered through the medium of the depressions 34 and 37 formed upon the opposite side of the chase sp that the ink will be applied to the type in the chase. Intermediate depressions 38 are formed in the outer annular track-way and arranged in opposed relation with .the depressions 35 so that the rollers which apply the green ink to the proper chase will be Araised and lowered at the proper time. Outer depressions 39 are formed in the outer annular track-way and arranged in opposed relation with the depressions 36 which cooperate to raise and lower the rollers that apply the red ink to the proper chase. Mounted upon the table 6 and arranged within the inner annular track-way is a gear ring 40 which cooperates with a bevel Q'ear 41 mounted upon the shaft 42, said shaft being journalled within suitable bearings 43 and mounted upon the'shaft is a cylinder 44 beneath which the type chasses pass for carrying out the printing operation, thus as the table 6 is rotated through the power applied to the shaft 9, the cylinder 44 is caused to rotate through the gear ring 40 and gea-r 41.

Formed upon the base member 2 intermediate the center and the outer edge are the spaced track rails 45 upon which the trucks 46 ride` the wheels of said trucks being arranged for movement upon the track rails 45. These trucks 46 which carry the type chases are loosely connected to lthe' table 6 through the medium of pins 47 yextending upwardly through suitable slots 43formedin the top of the table 6, said slots permitting a free movement of the pins 47 to compensate for the movement of the trucks during their passage over the rails 45 around the base 2. lt will be noted that upon rotationof the table 6, the trucks which carry the type chases will be moved around uponthe rails 45, but in order to cause the trucks'tofassinne a straight awayposition whilethey are passing beneath the cylinder 44. therails 45 are arranged inv spacedparallel. relation extending from a point to one side of the cylinder support to the other side, Alfthese straight away or parallel portions being generally indicated as at49, and it vwill be apparent from thisthatzwhenthe .forward wheels of the chase supporting trucks en- Mii) lfll

gage with these parallel portions, they will be caused to run in a straight line, as well as the rear wheels, causing the truck to pass beneath the cylinder in a straight away position wherein the cylinder and the type chase, when in contacting position will be arranged in parallel relation during the printing operation. It will be noted that by arranging the parallel portions 49 of the track rails beneath the cylinder 44, the trucks will be readily caused to assume a straight away position while passing beneath the cylinder 44, but will readily accommodate themselves to the circular trackway after having passed beneath the cylinder, the movement of the pins 47 in the slots 4S permitting a free movement of the trucksV when entering the straight away portion on passing therefrom.

By providing trucks such as illustrated in the accompanying drawings and forming a straight away portion in the track-way, beneath the printing cylinder, all guide arms and the like are eliminated.

In the operation of printing various colors with my improved machine, we will assume that the machine is to print three forms in red, green and blue, respectively, it being understood that the double discs shown in Fig. l will be replaced by a single disc 13. The chases containing the forms are mounted upon their respective trucks, the red being upon the forward truck in accordance with the direction in which the table is traveling, the green upon the second truck and the blue upon the third' truck, the proper colors are then placed within the fountains 16 and as the table rotates, the rollers through the several depressions in the inner and outer track-ways, will be lowered at the proper time to obtain inlz; from the proper discs. As illustrated in Fig. 1, all ofthe rollers are in position for contact withthe discs 13 being supplied with thel proper amount of ink and the proper color. As the chase containing the type for the red printing reaches the furthermost set of rollers, the depressions 36 and 39 will cause the rollers to move downwardly for engagement with the type in the chase,` applying the red ink thereto, this same operation is carried out with the chase containing the type for the green and blue ink, said type receiving its proper amount of ink from the respective rollers. Upon ret-urn of the chase containing the type for the red printing, the trucks will passJ beneath the cylinder 44, the straight away portions 49 of the truck causing the chases to be moved in their proper. relative positions beneath `the cylinder 44, whereby the ink which has been applied to the type within the chases will be transferred to the card or other material carried by the cylinder.

As set forth in the description aboveand illustrated in. the accompanying drawings, the single discs lmay be replaced by the doub-le discs 22, this being carried out by having the supporting arms 21 arranged within the bearing provided for the supporting pins 14 ofthe discs 13. `The fountains also can be divided equally by inserting the partition 23 should it be desired to print more than-three colors. I claim :l

1. In a device of the character described having a fixed base, a rotary table and a cylinder, a circular track-way onthe base having spaced parallel portions ,extending beneath the cylinder and a bed plate carriage rsupported by a truck operating 'on said track-way.

2. In a device of the character described having a fixed base, a rotary table and a cylinder, a circular track-way on the base having spaced parallel portions constituting a straightaway section extending beneath rthe cylinder and a bed plate carriage compris-I ing a body slidable radially relative the rotary table and adapted to be engaged and operated thereby and a truck part pivotally `connected to said body said truck having traction wheels engaging the track-way to positively support and guide the bed plate 'therefrom substantially as specified.

3. In a deviceof the character described the combination of a iXed base, a rotary table. a cylinder supported from the 'base over thetable, a bed plate, means for supporting the bed plate directly from the base comprising a truck having-traction wheels and guiding means for the bed plate comprising tracks carried by the base.

In testimony whereof I afix my signature.
